WILLIAM ROBERT GARNER, OF PALESTINE, TEXAS.

NUT-LOCK.

i Application led March 31, 1909. Serial No. 486,874.

To all whom it 'may concern:

Be it known that I, VILLIAM ROBERT GAR- NEE, a citizen of the United States, and a resident of Palestine, in the county of Anderson, State of Texas, have made certain new;

and useful Improvements in Nut-Locks, of which the following is a specification.

This invention is an improvement in nut locks especially inthat class of `nut locks and plates designed for use on railroad joints, frogs, cars, bridges and the like as well as in engines, iron fencing, buggies, wagons and otherwise where similar locks can be employed; and the invention consists in certain novel constructions, and combinations of parts as will be hereinafter described and claimed.

ln the drawings Figure 1 is a face View, and Fig. 2 is an edge view ofa nut lock plate embodying my invention. Fig. 3 is an edge view of the plate'showing some of the lugs adjusted 'to `position to lock a nut. Fig. 4 is an edge view of the plate illustrating the spring deflection thereof from a central point, and Figs. 5 and 6 are respectively, face and sectional views illustrating a timber lock nut washer, all of which will be described.

The plate A, see Figs. 1 to 4c, is provided with bolt holes B, and may have its ends deliected from a central point A as shown in Fig. 11 to hold the parts in close contact when the nutsv are screwed home. This deflection of the plate A from a central point A provides for the bearing of the said plate on the splice bars which are between the bolts so that when the nuts are screwed to a bearing, the plate will through the spring action thus produced hold the parts in close contact and prevent any motion or unnecessary wear of the different parts.

The plate A surrounding the bolt holes B is slotted at B radially outwardly from the said bolt holes and this slotted portion surrounding the bolt holes B is stamped or punched outwardly in convex form, see Figs.

2 and 3, forming aspring seat for the nuts,

thus providing for taking up such lost motion as may occur between any of the parts,

and the edges formed by the slots .B will afford a somewhat rough bearing for the nuts as the latter are turned home, thusv increasing the locking actionhresultingfrom the spring of the convex portions of the locking plate. Adjacent to these conveXed portions B2 of the locking plates I punch Specification of Letters Patent.

' from the said locking plates lugs, O- whose free ends are remote 4from the conveXed portions B2, so the said lugs C can be turned upwardly along side the nut D as shown in Fig. 3., to securely lock the saidY nut from turning on its bolt E.'

In Figs. 5 and 6 I illustrate a timber lock nut washer in which the plate A10 corresponding to the plate A in Fig. 1 has a bolt hole Bw from which radiate slots B11 and the portion B12 of the washer surrounding the hole B10 is convexed as in Fig. 1,

vthe plate A10 being provided with projecting lugs Ct, some of which may be turned up `to bear along side a nut as shown in Fig. 6,

while others may be pressed down into the wood F as shown in Fig. 6, to lock the plate from turning.

I claim- 1. The nut locking plate herein described bent at its middle portion, and inclined generally from said intermediate portion out wardly toward its opposite ends forming lforwardly springing arms on opposite sides of said intermediate bend, and provided in said arms with bolt holes, with conveXed portions surrounding said bolt holes and `slotted therefrom and having adjacent to saidV conveXed slotted portions lugs adapted to be bent alongside a nut seated against said convexed portions, all substantially as and for the purposes set forth.

2. A nut locking plate having bolt holes, convexed portions surrounding said bolt holes and slots leading from said bolt holes and subdividing the conveXed portions and provided in line between the said slots and outside of the conveXed portions with lugs j adapted to be bent alongside a nut seated on said conveXedV portion, substantially as set forth.

3. A nut locking plate having a bolt hole, a conveXed portion surrounding the bolt hole, and slots leading from the bolt hole and subdividing the convexed portion, and a lug or lugs `adjacent to said conveXed por tion and outside the same, and in line between the slots of the conveXed portion and .adapted to be bent upwardly along side a nut seated on said conveXed portion, substantially as set forth.

wiLLiAM ROBERT GAENER.
